PART I of III — Sally Miller’s past makes her a danger to Hillary Clinton’s future.

As Bill Clinton’s former lover tells The American Mirror, Miller’s background in television and radio equips her to effectively critique the Democratic front runner for president — not to mention spill the secrets Bill told her during their three-month affair in 1983.

We recently spent several hours with Miller, where she talked about her time in Arkansas and she recounted the time she spent with Clinton when he was governor. Miller says Bill would come to the back door of her previous Little Rock home for their trysts, where he would wear her black nightie and play his saxophone while she played the piano.

And in the course of our discussion, she told us how the sitting governor would snort cocaine off her coffee table.

“I was the older woman,” she says. “I’m seven years older than Bill and I think that’s the reason he confided in me because, you see, his mother was the central part of his world, his life, and he didn’t ever really have a strong father figure.

“I think he felt like he could talk to me like he would talk to his mother.

“We laughed a lot and we had fun,” Miller recalls. “Of course, he didn’t need it, but I think it may have become a habit that he smoked marijuana and that he did coke,” Miller says, knocking on the coffee table sitting in front of her.

“I just realized this is the table. It’s funny just sitting here — all my furniture I’ve collected through the years, but this is the couch he sat on, and that’s the table.”

It was a stunning moment that flies in the face of what America knows about Bill Clinton’s drug use.

After all, much was made of Clinton’s admission in 1992 that he tried pot when he was studying at Oxford University and he didn’t like it — and “didn’t inhale.”

Miller proceeded to provide The American Mirror with a thorough account of the governor snorting cocaine off her furniture.

“When he did coke,” Miller says, “he brought a little — like a woman’s cosmetic case, that’s the only thing I can describe.

“And he put it down here, pushed everything aside. And he rolled it out and there was this little mat and he sprinkled this white powder.

“I was sitting across the way and I was just fascinated because it had a little straw and he leaned over and — ” Miller says, bending over the table and pretending to injest, “you know, in each nostril.”

“He took a few big snorts and he felt better, I guess, because he had a big smile on his face.

“I asked him if he did coke because it was almost like a stimulant. He said it just made him feel better, gave him more power, made him feel courageous.

“I didn’t question it because everybody has different ways of getting high. I go running and I get a high,” Miller says, referring to her past days of regularly running to stay fit.

“If you ever saw pictures of Bill, he didn’t run much,” she says, smirking. “But he did do coke.”

A 1994 documentary titled, “The Clinton Chronicles,” deals extensively with allegations that Bill Clinton looked the other way as cocaine was trafficked through Mena, Arkansas.

“Dr. Suen, a doctor at the medical center here in Little Rock that’s taken care of Bill Clinton for his sinus problems, which may indeed be drug related to cocaine use, as they destroy the sinus passages,” Dr. Samuel Houston says in the film. “Gov. Bill Clinton was taken into the hospital, I believe it was the medical center, on at least one or two occasions, for cocaine abuse and overdosage, in which he actually had to be cared for at the hospital.”

A woman who said she provided cocaine for Clinton’s parties also appears in the film.

“I worked at a club called Le Bistro’s, and I met Roger Clinton there, Gov. Bill Clinton, a couple of his state troopers that went with him wherever he went,” Sharline Wilson says in “The Clinton Chronicles.”

“Roger Clinton had come up to me and he had asked me could I give him some coke, you know, and asked for my one-hitter, which a one-hitter is a very small silver device, O.K., that you stick up into your nose and you just squeeze it and a snort of cocaine will go up in there. And I watched Roger hand what I had given him to Governor Clinton, and he just kind of turned around and walked off. And that’s one specific.”
